No. 860,126. I

To allwhom it may v Be it known that 1, Joint MI. CAGE, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements insubmarine Boats, of which the following is a specification.

This invention relates to submarine boats, its prin- 3 governed. Iattain this object by the mechanism illuscipal object being to.-prod1icesimpleand effective;

means under control of the operapor'by; which the course of the boat in various directions may. readily be tratedin the accompanying drawings in the various views of which like parts are similarly designated and'in which! Figure .1-repre'sents a plan .view of a submarine boat equipped with my improved steering means, Fig. 2a side elevation thereof, the rudders having been shown in three positions, Fig. 3-ahorizontal, longitudinal section taken along a line 3-3, Fig. 2 and Fig. 4 an enlarged vertical cross section taken along a line 44, Fig. 2.

Referring to the drawings, represents the 'cigarshaped shell or hull 'of'a; submarine boat, access to the interior of which may be had by means of a normally hermetically closed hatch 6 opening in the upper surface of the conning-tower 7. I

The boat may be propelled while upon 'or under the surface of the water by means of four screw-propellers 8, while its vertical movements are controlled by'the.

horizontal submerging-screws 9, which are revolubly mounted inside vertical, transversely arranged funnels 10. e

Both modes of propulsion have been made subjects of separate applications for patent. v

The interior of the boat is divided into two compartments 11 and 11", which are used respectively as operating and engine rooms. The latter which is preferably locatedin the middle of the boat, contains the gasolene engine 12 which operates a dynamo electric machine or generator 13 by fiieansof which thevarious motors employed to actuatethe propelling and submerging appliances are energized.

The steering apparatus consists of two horizontal planes or rudders 14, which extend longitudinally along the sides of the boat, and are pivotally mounted thereon by means of central laterally extending shafts l5. Rudders 14 are preferably located above the longitudinal center line of the boat and are strengthened by judiciously applied truss rods 16, to enable them to withstand the pressure caused by the resistance of the water through which the boat is moved.

' Specification of Letters Patent. Application filed February 21,1906. SerialNo- 302,243.

,"Patented July 16,1907.

At the points where shafts 15 project through the "sides of the vessel, stufling boxes 17 have been applied to insure water-tight joints, the'said boxes having been made sufliciently large and heavy to act as journal bearings for the shaitsextending through them.

To incline the rudders in either direction, shafts 15 may be rotated by'means of hand wheels 18 secured to the upperflextremities of vertical shafts'lll which are revolubly mounted in suitablebearings 20 and are preferably located in the conning tower of the boat.

The lower extremities of shaftslil are provided with bevel gear wheels 21 which, meshing into correspond 'ing wheels 22-secured to the inner extremities of the horizontal shafts 15, cause the latter to rotate when the hand wheels are being turned. I is simple and willbe The operation of the rudders readily understood.

'- To submerge the vessel the rudders are inclined .to-

wards the prow of the boat '(position A A, Fig. 2, so as to depress its nose and to cause it to descend, while the upward movement of the shell may be .'at tainedby reversing the position of the rudders, as shown at B B, Fig. 2. I

When it is desired to turn the boatthe ruddeij on the side towards which the vessel is to be directed, is placed in the forward inclined position and the other rudder is simultaneously tilted in opposite direction.

'Theplanes may furthermore be employed to act as brakes when the vessel is propelled'upon the surface of the Water'and, during submergence of the .boat, they aid in supporting and retaining it at the required depth.

- The switches and rheostats, as well as the various electrical connections between the motors and dynamos have been omitted from the drawings to avoid confusion. I

c Having thus'described my invention what I claim is:

1. In a submarine boat the combination with the normally water tight shell, of centrally pivoted, independently movable, horizontal planes extending longitudinally along its sides pivoted at the longitudinal center of the boat.

2. In a submarine boat, the combination with a water tight shell, of horizontal planes extending longitudinally 'along its sides and arranged to be revolvedin opposite JOHN M. CAGE.
